APPARATUS FOR WATERING COKE IN COKE-OVENS.

b all whom it may concern:

Be it known that we, W'ILLIAM L. Arran- "nnu' and Mann Gon'roN, of Brownfield,

Fayette county, and State of Pennsylvania, have invented a new and usefpl Improvement in Apparatus for \Vatermg (Joke 1n Cokefivens, of which the followin 1s a full, clear, and exact description, re erence is a side elevation of the apparatus on a 'larger scale and looking at it from the opposite side from Fig. 1. Fig. 3 is a detail view showing the slide mounting .of the watering apparatus on the truck. Fig. a is -an end view partly in section, the section being on the line IVIV of Fig. 1. Fig.

5 is a top plan view; and Fig. 6 is a detail view showing the automatic cut ofi.

Our invention has relation to apparatus for water ucnchin coke in coke ovens scribed more particularly rectangular ovens, and is an improvement upon the apparatus for this purpose which is described and claimed in our Patent No. 949,290, dated Feb. 15,

In that application we have doand claimed apparatus of this character comprising a hydraulic motor hav ing its piston provided with a sprinkling head designed to be reciprocated within the coke oven, together with means whereby the water which actuatcs the motor is sub;-

sequently discharged by the sprinkler head and used for quenching the coke.

()ur present invention, while retaining this feature, is designec'l to increase the ra iditvof the quenching operation by provicin'g additional. sprinkling meanswhich operate in conjunction with the first named means.-

A further object of our invention is to i provide an improved mounting for the apparatus whereby a full stroke of the sprim kler heads may be obtained within the oven and. which, after the quenching operation ;has,been completedin any one oven, w ll permit the apparatus to be withdrawn a sufficient distance to clear the oven doors in lnoving it to an adjacent oven.

Astill further object is to provide means Specification of Letters latent.

Application filed January 18, 1910. Serial No. 538.724.

' for automatically stopping the operation of the motor when the quenching operation has been completed in any oven.

The precise nature of our invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction, form, and arrangement of the various parts without departing from the spirit and scope of our invention as defined in the appended claims.

In these drawings the numeral 2 desig nates a coke oven of the rectangular type. In practice there is a series of these ovens placed side by side, and extending along each side of the series are'parallel tracks; one of these tracks is shown at 3. Mounted upon each track is a carriage or truck of any suitable construction and which may be propelled along the track to move the apparatus from one oven to another by any suitable motive power. In the .drawin we have shown a crank operated prope ling mechanism 6. The watering apparatus comprising our invention is mounted a on this truck or carriage; and it will be un erstood from the foregoing that in practice a similar apparatus is provided at each side of the series of ovens, the sprinkling heads beingarranged to enter doors at the respective sides of the ovens and to be reciprocatcd over one-half of the area of the coke beds therein. It will be understood, however, that if desired, the apparatus may be used at one side only of the oven and the sprinkler heads may be arranged to be reciprocated entirely across the oven.

I nasnn1ch as the watering apparatus at one'side ofthe series of ovens is a duplicate of that at the opposite side, we have shown and will describe but one apparatus. This apparatus comprises a cylinder 7 having therein a reciprocating piston carried by a hollow piston rod 8 which extends outward ly through a stuiiing box 9 at one end of the cylinder. )onnected to the projectin end of this hollow rod is a sprinkler hea 1.0 extending transversely of the rod and provided with a. plurality of discharge perforations 11, and terminating in backwardl dircctedcnd portions 12, also provided wit discharge erforations. The motor cylinder is provide( with a valve shifting motor or engine 13 of the general character described in our said patent. The pistonis also provided with valve means for admitting water from the exhaust side of the piston into the hollow piston rod to be thence discharged by the sprinkler head 10, such valve means being also preferably similar to that described in our said patent and having similar actuating connections 14, 15, 16, l7, l8 and 19. ,The motor which we have herein shown, is, in fact, of the same general t pc and mode of operation as that describcd m our said patent and need not be described herein in detail. a

designates a water supply pipe supported on the truck or carriage 4 and having a supply connection 21. The pipe 20 is connected with the pipe by the' pipe 2+1, and is also connected with the jront end portion of the cylinder by the pipe 24. The connection 2i is for the urpose of filling the front end of the cylinci er rn startin the ap aratus, and is rovided, with a and va ve 24" which is c osed as's'oon as the filling is completed and remains closed during the 0 eration ofthe a aratus. The valve chamber 23 is connecte to the rear valve chamber 22 by the longitudinal pipe 25 through. which water is sup lied to the two ends of the motorduring t e operation of the ap aratus.

The ollow piston rod and sprinkler head 10 are guided and supported in their reciprocatin movements by means of the two paralle? pipes 27 and 28 which are of a length greater than the length of the motor cylinder 51nd are arranged above said cyl-.

inder an parallel therewith. These pipes 27 and 28, which are arran ed to reciprocate with the hollow piston ro are mounted on suitable guides, preferably roller guides, such as 'indicated at 29, carried by suitable brackets 30 connected to the motor cylinder. The two pipes are further sup orted and made rigid with respect to eac other by means of the interposed brackets 31. The two pipes 27 and 28 are connected at both ends b means of the fittings or couplings 32 am 33. The fitting or coupling 32 is connected at one'end to the water supply pipe 20 by means of a flexible hose 34. The forward ends -of the two ipes 27 and 28 are also connected with eaci other and with the piston rod 8 by a rigid connection 35; and the fitting 33 has connected thereto a sprinkler head 36 which is located in front of and parallel with the sprinkler head 10, i

this head being similar to the head 10.

ST wherever seen designates a hand valve in the water supply connections.

3S designates drain cocks for the valve chambers 22 and 33.

3S) designates a valve placed in the pipe 20 and arranged to control the admission of water to the pipe 25 and also to the pipes 27 and 28.

In. theoperation of the apparatus, the

sprinkler heads 10 and 36 are reciprdcated E within the oven a sufiicient and predetertion has been completed, it is dcsirab e to provide automatic means for closin the valve 39 so as to stop the motor wit the sprinkler heads in their retracted positions. For this purpose we provide the lon itudinal reciprocating rod 40 which is s idably 7 supported in a suitable bearing 41 attached to the motor c lindcr and which is provided at its forwarc end with a suitable rojections-2 adapted to be engaged with t 'e connecting member 35 at the end of each back- 30 ward stroke of the sprinkler heads. This rod is provided with a returning spring 4 a which returns it to its normal position after each operation. Connected to the rod 40 is a pawl 43 which is arranged to engage the 5 teeth of a ratchet wheel 44 mounted upon one side of the motor cylinder, as best shown in Fi". (3. Loosely mounted on the shaft 45 of this wheel 44 is a lever arm 46 which is connected by a link 47 with an arm 48 on the stem of the valve 39. The wheel 44 is provided with a plurality of pinholes 49 arranged in a circular series, a pin 50 being provided to be inserted in any one of these holes according to the number of reciprocations which it is desired to give the sprinkler heads 10 and 36 in each oven before the motor is automatically stopped.

in operation, the rod 40 will be actuated at the completion of each return stroke of the sprinkler heads and through the pawl 43. will move the wheel 44 one tooth -for each complete reciprocation of the sprinkler heads. \Vhen the wheel 44 has been moved a sulliciont distance to cause the pin 50 to engage with the lever 46, the valve 39 is automatically closed. This stops the motor with the sprinkler heads in their retracted position and after they have made a complete return stroke. Byshifting the no position of the pin 50 it will be obvious .that this stop of the motor may be made to occur after any desired number of reciprocations within the limit of control of the wheel 4 4.

After the quenching operation has been completedin one oven, it is necessary to retract the sprinkler heads a sufficient dis-' j lance to clear the oven doors and allow the apparatus to be moved along the series of ovens to another oven. This might be new eomplished by causing the sprinkler heads to move entirely clear of the oven at the end of each return stroke. This, however, would result in loss of water during the time the sprinkler heads were outside the ovenon each stroke. To avoid this loss of water and at the same time accomplish the desired result above stated, we mount the motor cylinder in a shoe or saddle 51 (best .readil I 'quenc 111g operation, the slide can be 0 shown in Fig. 3) and which is slidably mounted u on suitable guides 52 on the truck 4. he shoe'or saddle is provided with a rack bar 53, whose teeth are en gaged by a pinion 5s on a transverse shaft 55 also mounted on the truck 4 and having an operating crank 56 at one end. By means of this sliding shoe or saddle, and the 0,, rating means therefor, it will be seen that after the completion of a erated to retract the sprinkler heads su ciently to clear the oven in being moved to another oven.

Theoperation of the apparatus will be readily understood from t e foregolnig description. At each reciprocation o the sprinkler heads water will be discharged across the entire width of the oven from each sprinkler head, the sprinkler head 10 receiving its supply of Water from the exhaust of the motor cylinder in the manner described in our said patent; While the head 36 receives its supply directly from the pipe 20, and this water being made to pass through the pipes .37 and 28 on its Way to the head 36. By providing these two sprinkler heads, we not only retain the advantages of the apparatus of our previous patent in utilizin the exhaust water from the mptor; but we argely increase the rapidity of the quenching operation. By passing t water for the head 36 through the pipes 27 and 28, these pipes are kept cool while in the oven.

After the sprinkler heads have made the reuired number of reciprocations'in any partlcular oven, the valve 39 1s automat1cally closed in the manner before described and the motor is stopped with the heads in their retracted position. The crank 56 is then 0 erated to move the apparatus back a su cient distance to cause the heads to clear the oven. The truck 4 is then moved along the track 3 to another oven; the shaft 55 is then operated to move the apparatus toward that oven; and the valve 39 is then manually opened to again start the motor.
